abstract = "In this project, an unknown system structure was
identified using the Genetic Programming technique. A
program was developed that, instead of combining linear
systems, evolves nonlinear ordinary differential
equations to describe a system. The solution space was
increased by using this approach. Automatically defined
functions were used to represent the ordinary
differential equations.
A new way was introduced to speed up the evolution of genetic trees. The genetic trees representing the equations were written in C notation to a file to be compiled by a C compiler and evaluated by the computer. This required modifications to the Genetic Programming kernel formerly used. The modifications facilitated evaluation of a complete generation at one time to minimise compiler overhead. In order to build up a C++ class hierarchy, the kernel was completely restructured. A lot of features like shrink mutation, variable tournament size, improved deme handling etc. were also added. A parameter study was carried out to investigate the influence of important control parameters.
The Genetic Programming system was applied to a known, nonlinear system to verify its ability. After this proved to be successful, the input/output response data of a helicopter engine was used to identify that system. Candidate models were derived from that analysis.",
